1 Answers
Subject 2 shoulder line varies depending on the car and the driver's seating position, and the window positioning may differ. It is advisable to find a car in advance and conduct an actual test to determine the exact position. As for the driver's seat position, the best position is like sitting on a sofa, with legs naturally extended and feet able to fully depress the clutch, brake, and accelerator pedals. The knees should not touch the steering column housing, and the lower back should be supported by the seatback. The arms should naturally extend forward to rest on the steering wheel, allowing the driver to reach the top of the wheel. The optimal seating posture for Subject 2 is as follows: 1. Correct seat height: The driver's view should not be obstructed by the steering wheel, and they should be able to clearly see the instrument panel, with at least a fist's distance between the head and the roof. 2. Seat front and back position: The hips should be pushed back as far as possible to touch the seat cushion and backrest, ensuring a stable seating position. 3. Leg bend: When the foot fully depresses the pedal, there should still be a slight bend in the leg, with 160° being the optimal angle. Both hands should be able to reach all positions of the steering wheel while maintaining a slight bend.
